FIG. 2 is a perspective view of a front cover of a waterproof case according to an embodiment of the present invention as viewed from the inside, FIG. 3 is a perspective view of a rear cover of the waterproof case according to an embodiment of the present invention as viewed from the inside, FIG. 5 is a partially enlarged view of part A of FIG. 4, and FIG. 6 is an exploded perspective view of a waterproof case according to an embodiment of the present invention .

Hereinafter, a waterproof case 200 according to an embodiment of the present invention will be described with reference to FIGS. 2 to 6. FIG.

The waterproof case 200 according to an embodiment of the present invention includes a front cover 210 having a transparent front window 213 and covering a front surface of the terminal body 104, And a rear cover 220 for defining the inner space and accommodating the terminal body 104 in the inner space.

In this case, the front cover 210 and the rear cover 220 must be closely contacted to prevent the inflow of liquid such as water into the inner space. For this purpose, in one embodiment of the present invention, A protrusion 214 is formed on the inner surface of the front cover 210 and a through hole 223 is formed on the outer surface of the rear cover 220 . At this time, a plurality of the protrusions 214 and the through holes 223 are formed, and the protrusions 214 are inserted and fixed in the through holes 223, so that the rear cover 220 is coupled to the front cover 210 .

The rear cover 220 may be formed to have the same size as the front cover 210. In order to insert the rear cover 220 into the front cover 210, (210) is formed larger than the rear cover (220).

The elastic members 216 and 226 are provided at portions where the front cover 210 and the rear cover 220 are in contact with each other so that the space defined by the front cover 210 and the rear cover 220 To prevent infiltration.

2 to 6, the hinge unit 215 is formed at the upper and lower ends of the waterproof case 200, but the present invention is not limited thereto. The hinge unit 215 may be formed at either the upper end or the lower end, As shown in FIG.

The hinge portion 215 is formed at the upper and lower ends of the waterproof case 200 and the hinge portion 215 formed at the lower end is described with reference to the hinge portion 215 formed at the upper end Let's do it.

The hinge part 215 includes a flange part 211 constituted by a pair of protruding parts 211a and 211b and a hinge shaft 212 and a hook 215a. The flange portion 211 is formed at an upper end and a lower end of the front cover 210 and is spaced apart from the front cover 210. The flange protrudes from the front cover 210 and a hole 212a is formed therein.

The hinge shaft 212 penetrates through one end of the hook 215a to be a center of rotation and the other end of the hook 215a is formed to rotate around the hinge shaft 212. [ Both ends of the hook 215a are connected to the flange 211 by inserting and fixing both ends of the hinge shaft 212 into the pair of protrusions 211a and 211b. The flange 211 is formed at the upper end and the lower end of the front cover 210 by forming the front cover 210 to be larger than the rear cover 220. However, when the front cover 210 is smaller than the rear cover 220 The flange portion 211 may be formed on the rear cover 220. In this case,

Although the through holes 212a are formed in the pair of protrusions 211a and 211b, the protrusions 211a and 211b may be formed in a groove and may be formed at both ends of the hinge shaft 212 May be inserted. In the case of such a groove, the end of the hinge shaft 212 is inserted but is not exposed to the outside.

The hook 215a is fixed to the rear cover 220. The rear cover 220 is formed with a groove 231 having a width corresponding to the hook 215a. 5, the hook 215a is formed with a bent portion 215b bent along the outer surface of the rear cover 220 and bent perpendicularly toward the rear cover 220 The bent portion 215b is received and fixed in a groove 231 formed on the outer surface of the rear cover 220. [

The inner space defined by the front cover 210 and the rear cover 220 is sealed by fastening the front cover 210 and the rear cover 220 to each other, Protrusions 214 are formed on the inner side of the cover 210 and holes 223 are formed on the outer side of the rear cover 220 at positions corresponding to the positions of the protrusions 214, The cover 210 and the rear cover 220 are fastened together. Since the front cover 210 and the rear cover 220 form the protrusions 214 and the holes 223 for fastening, holes are formed in the inside of the front cover 210, A protrusion may be formed on the outer side of the protrusion 220.

However, since the front cover 210 has a larger area than the rear cover 220, the rear cover 220 is inserted into the front cover 210 while being inserted. Therefore, the protrusion formed on the outer side of the rear cover 220 can be exposed to the outside of the hole, thereby avoiding the design. Therefore, in one embodiment of the present invention, the protrusion 214 is formed inside the front cover 210, and the through hole 223 is formed on the side surface of the rear cover 220. At this time, if the rear cover 220 is formed to have a sufficient thickness, it may be formed in a groove instead of the through hole 223.

A plurality of holes 214 and protrusions 223 may be formed along the side surfaces of the front cover 210 and the rear cover 220. The front cover 210 and the rear cover 220, The front cover 210 and the rear cover 220 can be coupled to each other by the fastening force of the hinge portion 215 without being formed at the upper and lower ends of the cover 220. However, the protrusions and holes are not limited to the upper and lower ends of the front cover 210 and the rear cover 220.

The side surfaces of the front cover 210 and the rear cover 220 should be formed higher than the side surfaces of the terminal body 104 because the front cover 210 and the rear cover 220 must accommodate the terminal body 104 . Since the front cover 210 and the rear cover 220 accommodate the terminal body 104, it is preferable that the front cover 210 and the rear cover 220 have a shape corresponding to the terminal body 104.

In an embodiment of the present invention, the front cover 210 and the rear cover 220 may be integrally coupled to each other to house the terminal body 104 to serve as the waterproof case 200, The battery cover 103 of the terminal body 104 may be used as a function of the battery cover 103 by fastening the terminal cover 104 to the terminal body 104. [ 3, a plurality of hooks 224 are formed on the inner side of the rear cover 220, and hooks 224 are formed on the edge of the terminal body at positions corresponding to the hooks 224 A plurality of grooves 131 (see Figs. 10 and 11) that can be inserted are formed. At this time, since the rear cover 220 covers the side surface of the terminal body, the thickness of the rear cover 220 is similar to the thickness of the terminal body. 10 and 11, the rear case 102 has grooves 131 formed therein.

In addition, in order to prevent the thickness of the front cover 210 or the rear cover 220 from being thickened when the front cover 210 or the rear cover 220 is fastened to the terminal body, the rear cover 220, from which the battery cover 103 is removed, Respectively. That is, the terminal body 104 includes a front case 101 and a rear case 102 which defines an inner space in which the electronic parts are mounted by being coupled to the front case 101. The rear case 102 Is covered by the battery cover 103. [ The battery cover 103 is exposed to the rear surface of the terminal body 104. When the rear cover 220 according to an embodiment of the present invention is used, the rear case 102 is covered by the rear cover 220, and the battery cover 103 is removed do.

Connection terminals such as a pogo pin and a C-clip for electrically connecting the NFC antenna or the electronic components are formed on the inner surface of the battery cover 103, The connection terminals 241 formed on the inner surface of the battery cover 103 are formed on the inner surface of the rear cover 220 to fasten the rear cover 220 in a state where the battery cover 103 is removed .

1C, a rear input unit 125, a camera 121b, an LDAF 126, a laser detection auto focusing system, a flash 124, And the output unit 152b are exposed to the outside so that the rear cover 220 can be used in place of the battery cover 103. The rear cover 220 is also connected to the rear input unit 125, The through holes 222a, 222b, 222c, and 222d are formed so that components such as the camera 121b, the autofocus device 126, the flash 124, and the sound output unit 152b are exposed to the outside. That is, the rear cover 220 is formed with a plurality of through holes 222a, 222b, 222c, and 222d at positions corresponding to the components so that the components are exposed to the outside, such as the battery cover 103. At this time, transparent windows 229a, 229b, and 229c may be formed in some of the through holes 222a, 222b, and 222c of the through holes, so that normal shooting can be performed in water. Since the transparent windows 229a, 229b, and 229c are formed on the rear cover 220, they may be referred to as rear windows.

The autofocusing unit 126 measures a distance using a laser, and includes a light emitting unit for transmitting a laser beam and a light receiving unit for receiving a laser beam. A distance is measured using a phase difference between an output signal to be transmitted and a reception signal to be received, and at the same time, a function of automatically focusing when photographing or photographing a moving image is performed.

That is, in the conventional auto focusing system (AF), it takes time to cover the entire image by focusing on the image without using a laser. However, the autofocus apparatus measures the distance by phase difference through the laser, , And otherwise, it is processed by the conventional AF method.

Particularly, since the sound should be leaked to the outside through the sound output unit 152b and be waterproof, a waterproof mesh 227 is applied to a portion of the rear cover 220 covering the sound output unit 152b. . The waterproof mesh 227 is made of a material that transmits sound but can block liquid such as water. For example, it can be formed of a gortex material. As described above, since the portion covering the sound output portion 152b is made of a Gore-Tex material, water is prevented from flowing outside the rear cover 220 and the sound leaks to the outside of the rear cover 220 .

The rear input unit 125 includes a first button unit 125a receiving a push input of a first function and keys disposed on both sides of the first button unit 125a, And second button portions 125b and 125c receiving push inputs of different second functions to detect the input of control commands. That is, the first button portion 125a and the second button portions 125b and 125c have three depressed portions, and the depressions 221a, 221b, 220).

The presser foot 221 is provided on the inner side of the rear cover 220. The first and second pressing protrusions 221a and 221b are provided at positions corresponding to the first and second button parts 125b and 125c, , 221c are formed. The first button portion 125a or the second button portions 125b and 125c are pressed when the first pressing projection 221a or the second pressing projections 221b and 221c are pressed. The second pressing protrusions 221b and 221c include an upper pressing protrusion 221b and a lower pressing protrusion 221c.

The pushing protrusions 221a, 221b, and 221c may be integrally formed, or may be made of an elastic material. At this time, the camera window 229a and the lifting base 221 may be formed by the same bracket 235. [

Hereinafter, a structure for waterproofing the front cover 210 and the rear cover 220 will be described.

5 is an enlarged view of the upper ends of the front cover 210 and the rear cover 220. Referring to FIG. 5, the contact portions of the front cover 210 and the rear cover 220 are provided with first and second elastic members (216, 226). The first and second elastic members 216 and 226 are formed along the shapes of the front cover 210 and the rear cover 220 to seal the space defined by the front cover 210 and the rear cover 220 .

A first elastic member 216 is provided at the upper end 210a of the front cover 210 and the first elastic member 216 is provided at the upper end of the front cover 210 and the rear cover 220, A first elastic protrusion 216a protruding toward the rear cover 220 is formed. The first elastic protrusion 216a contacts the upper end 220a of the rear cover 220 to seal the front cover 210 and the rear cover 220 in a primary manner. A second elastic member 226 is provided on the inner side of the upper end 220a of the rear cover 220 and a terminal body 104 is received on the rear cover 220. The second elastic member 226 The main body 104 and the rear cover 220 are sealed by sealing the back cover 220 and the terminal body 104 by a sealing member (not shown).

The second elastic member 226 is formed with a second elastic protrusion 226a protruding toward the inside of the terminal body 104 so that water is not introduced into the side and rear surfaces of the terminal body 104. A waterproof tape 217 is provided at a part of the upper end 210a of the front cover 210 so as to prevent water from being introduced into the front cover 210. [ do. The second elastic protrusions 226a protrude toward the front surface of the terminal body 104. The second elastic protrusion 226a is in close contact with an upper end portion of the terminal body 104 so that water does not flow into the terminal body 104. [

The upper ends 210a and 220a of the front cover 210 and the rear cover 220 are fixed to the terminal body 104 by the first elastic member 216, the second elastic member 226, and the waterproof tape 217. [ ) To block the liquid that may flow into the liquid.

8 is a sectional view of a waterproof case 200 in a state where the front cover 210 and the rear cover 220 are coupled to each other according to an embodiment of the present invention. will be.

9, the first elastic protrusion 216a of the first elastic member 216 formed on the inner surface of the front cover 210 protrudes toward the rear cover 220, (220b) to seal a space between the front cover (210) and the rear cover (220). At this time, protrusions 2201 and 2202 are formed on the upper surface 220b of the rear cover 220 so that they can be more firmly sealed. That is, the first elastic protrusion 216a is disposed between the protrusions 2201 and 2202, thereby sealing the gap between the front cover 210 and the rear cover 220 more firmly.

A third elastic member 228 is formed on the outer surface of the rear cover 220. The third elastic member 228 is formed to protect the terminal body 104 from an external impact. 9, the third elastic member 228 may be integrally formed with the second elastic member 226. In order to form the third elastic member 226, the double injection method may be applied in an embodiment of the present invention. can do. That is, the rear cover 220 is manufactured, a through hole 237 is formed in a side portion of the rear cover 220, and the third elastic member 228 is attached to one side of the through hole 237 . At this time, a side end portion 236 of the rear cover 220 is protruded so that the third elastic member 228 is not separated from the rear cover 220. The second and third elastic members 226 and 228 may be integrally formed and the rear cover 220 may be formed more firmly by preventing the second and third elastic members 226 and 228 from being separated from the outside by being caught by the protrusion 236. [

This also applies to the case of the first elastic member 216 as well. That is, the first elastic member 216 is also formed on the front cover 210 in a double injection manner.

The first to third elastic members 216, 226, and 228 may be any one of urethane, rubber, and silicone, but is not limited thereto. The same can be applied to the above-mentioned elevator base 221 as well.

In order to allow the front cover 210 or the rear cover 220 to recognize the fastening of the terminal body 104 when fastened to the terminal body 104, the front cover 210 or the rear cover 220 And the terminal body 104 is provided with a mounting sensor 271 capable of detecting a magnetic force change by recognizing the magnetic member 230. A Hall sensor (not shown) may be used as the mounting sensor 271. The magnetic member 230 may be formed on one of the front cover 210 and the rear cover 220, Or may be formed on both the front cover 210 and the rear cover 220.

That is, the mounting sensor 271 is formed inside the terminal body and recognizes that the front cover 210 or the rear cover 220 is fastened to enter the waterproof mode.

If only one magnetic member 230 is present, it may be formed inside the front cover 210 as shown in FIG. When the magnetic force is changed due to the detachment of the magnetic member 230, the hall sensor senses the magnetic force and recognizes detachment of the front cover 210 or the rear cover 220. Since the rear cover 220 is used in place of the battery cover 103, the rear cover 220 of the waterproof case 200 is always fastened to the terminal body 104, Since the magnetic member 210 is fastened to the terminal body 104 only when used in water, the magnetic member 230 may be disposed on the rear cover 220.

Although the rear cover 220 can not completely block the terminal body 104 from liquid completely, when the rear cover 220 recognizes that the rear cover 220 has been fastened, the mobile terminal 100 enters the waterproof mode. As described above, when the user enters the waterproof mode, the display window 151c of the window 151a of the mobile terminal 100 is displayed in the waterproof mode.

Meanwhile, in one embodiment of the present invention, touch input may be a problem to the mobile terminal 100 in a state where the waterproof case 200 is fastened to the terminal body 104. [

The touch sensor in the mobile terminal 100 may be of an electrostatic type or a static pressure type. The electrostatic type changes the electric field when the conductive object approaches the touch screen. By recognizing the electric field change at this time, Method. In recent years, the window of the mobile terminal 100 is mainly made of tempered glass. When the tempered glass is used, the touch can be recognized electrostatically.

The static pressure type is a flexible window material such as acryl, so that when the user presses the acrylic window, the pressed portion is recognized by the touch sensor and the touch of the user is recognized. When it is a static pressure type, it can be freely used in water because it does not involve electric field change.

In order to pressurize the touch sensor of the mobile terminal 100 even in the case of the static pressure type, the front window 213 of the front cover 210 must be strongly pressed. When the front window 213 is strongly pressed, The window 213 may be broken.

As described above, the use of the front cover 210 may cause the user's touch recognition to be difficult. In order to prevent this, the touch sensitivity is improved in an embodiment of the present invention. That is, when the mobile terminal 100 enters the waterproof mode, the touch sensitivity is improved so that the touch can be recognized without strongly pressing the front window 213.

In the normal mode, an area corresponding to the fingerprint of the user's finger must be recognized to recognize the touch. When the area below the fingerprint is recognized, the fingerprint is recognized as a non-recognition or malfunction. In the waterproof mode, the user does not recognize all of the area corresponding to the fingerprint of the user, but recognizes the area even if the area is recognized as the touch input of the user. In this way, the touch recognition area is adjusted to be smaller than that in the waterproof mode in the normal mode, thereby responding sensitively to small touches.

More specifically, a capacitive touch sensor will be described as an example.

The capacitive touch sensor detects the touch based on the electromotive force through the human body. When a part of the human body touches the touch sensor, the surface electromotive force is detected through the charge / discharge of the capacitor, It is a sensor that operates.

When the human body is brought into contact with the human body, the electrostatic capacity is changed finely. Thus, the difference between the change value and the set value can be sensed and evaluated with high sensitivity or low sensitivity. If the difference between the change value and the set value is set small, , And if the difference between the change value and the set value is set large, it can be estimated that the touch sensitivity is low. Thus, the touch sensitivity can be controlled by adjusting the difference between the change value and the set value. At this time, since the electrostatic capacity is proportional to the area and inversely proportional to the distance, if the touch sensitivity is improved, even if the touch area is small, the touch is recognized. That is, by reducing the touch recognition area, the touch sensitivity of the touch sensor can be improved.

14 is a block diagram of a waterproof case 200 according to an embodiment of the present invention. The waterproof case 200 includes a sensing unit 270, a communication unit 240, an input / output unit 250, and a lifting base unit 221. There is also a case where the auxiliary battery 290 is provided.

The control unit 280 may receive the information collected by the sensing unit 270 and the input and output unit 250 and may transmit the received information to the terminal body 104 through the communication unit 240, Sound can be output through the unit.

The communication unit 240 is a device for transmitting and receiving information to and from the terminal body 104 when the terminal body 104 is mounted on the waterproof case 200. The communication unit 240 may transmit a signal in a wireless manner such as a Bluetooth 246 or an NFC And a wireless communication unit 240 for transmitting and receiving data.

The Bluetooth and the NFC 225 (Near Field Communication) are capable of wireless communication between devices in a short distance, and can transmit and receive data and signals through the wireless communication unit 240.

Since the NFC 225 detects a case where it is located at a short distance of 10 cm or less, the terminal body 104 equipped with the NFC 225 can sense it when it is mounted, and as the mounting sensor 271 of the sensing unit 270 Can play a role.

The sensing unit 270 senses the state of the waterproof case 200 and generates a signal. The signal generated by the sensing unit 270 may be transmitted to the terminal body 104 through the communication unit. The sensing unit 270 may include a mounting sensor 271 for sensing whether or not the terminal body 104 is mounted, a water immersion sensor 273 for sensing whether the waterproof case 200 is in the water or the like.

The mounting sensor 271 is a sensor for detecting whether or not the terminal body 104 is mounted on the waterproof case 200. The mounting sensor 271 can detect whether the terminal body 104 is mounted or not by using the NFC 225 described above, The hall sensor provided in the terminal body 104 senses the magnetic member 230 provided in the case 200 to sense that the terminal body 104 is mounted on the waterproof case 200. [ Or vice versa.

The water immersion sensor 273 is a sensor for detecting whether the waterproof case 200 is in the water. The water immersion sensor 273 can detect the refractive index at which the ambient light is incident by using the optical sensor to determine whether water or air is in the air. The water immersion sensor 273 may be provided in the waterproof case 200 to sense which part has entered the water.

The input / output unit 250 may include a lifting base 221 and a waterproof mesh 227. Since the input of the touch sensor of the mobile terminal 100 is limited, the push rod unit 221 may be provided in a separate manner. The lifting case 221 may be provided in the waterproof case 200 to transmit a user command inputted through the communication unit 240 to the mobile terminal 100. [

Since the sound output from the terminal body 104 is blocked by the waterproof case 200, the sound signal is received through the communication unit 240 and the sound is output through the waterproof mesh 227 provided in the waterproof case 200 can do.

The auxiliary battery 290 can supply power to the mobile terminal 100 and increase the use time of the mobile terminal 100 through the auxiliary battery 290. [

Hereinafter, a control method of the mobile terminal 100 in the waterproof mode will be described.

First, when the fastening of the front cover 210 or the rear cover 220 is recognized by a hole sensor (not shown), which is an example of the magnetic member 230 and the mounting sensor 271, . The waterproof mode at this time includes a case where the front cover 210 and the rear cover 220 are fastened to the terminal body 104 or only the back cover 220 is fastened to the terminal body 104. That is, when the rear case 102 of the terminal body 104 is covered with the rear cover 220, it is regarded as a waterproof mode.

12 shows a state in which only the rear cover 220 is fastened to the terminal body 104 according to an embodiment of the present invention and is switched from the air to a waterproof mode. The front cover 210 and the rear cover 220 according to the embodiment are fastened to the terminal body 104 to receive the terminal body 104. When the mobile terminal 100 is in the waterproof mode FIG. 13 shows a state in which a part of the mobile terminal 100 is locked.

As shown in FIGS. 12 and 13, when entering the waterproof mode, a message indicating that the waterproof mode is to be displayed is displayed on the message window 151c of the window 151a.

In the normal mode, the user presses the upper button 125b of the second button 125b or 125c to enter the camera mode and the user presses the lower button 125c to enter the memo creating mode. When the front cover 210 or the front cover 210 is coupled to the terminal body 104 and enters the waterproof mode, one of the upper button 125b and the lower button 125c enters the front camera mode, And enters the rear camera mode when the other one is pressurized. For example, when the upper button part 125b is pressed, the front camera mode is entered. When the lower button part 125c is pressed, the rear camera mode is entered.

When switching from the normal mode to the waterproof mode, the user can enter the front camera mode or the rear camera mode automatically. In the case of entering the front camera mode (self camera mode), the window 151a corresponds to the angle of view of the front camera Screen may be displayed. When the lower button 125c is pressed in the front camera mode, the camera is switched to the rear camera mode.

On the contrary, when switching to the waterproof mode, the screen is automatically displayed in the window 151a when the rear camera mode is entered and the waterproof mode is changed to the waterproof mode. In order to switch to the front camera mode, (125b).

In order to switch between the front camera mode and the rear camera mode, the long press time of the upper button part 125b or the lower button part 125c is approximately 1 to 3 seconds, and the first button part 125a is pressed , The photograph can be taken.

Alternatively, in an embodiment of the present invention, the front camera mode and the rear camera mode can be switched by repeatedly pressing the upper button part 125b or the lower button part 125c. For example, when the camera enters the front camera mode automatically when switching from the normal mode to the waterproof mode, the camera is switched to the rear camera mode when the upper button 125b is pressed once, can do. It is possible to switch the front and rear camera modes in the same manner using the lower button portion 125c.
